To all whom it may concern:

Be it known that I, WALTER B. Asrnnr, a citizen of the United States,-residin at Glas ow, in the county of Barren and tate e'ntucky, have invented certain new and useful Improvements in Rewinding Machines for Moving-Picture Films, of which the followin is a specification.

This invention re ates to re-winding machines for moving picture films and has for its object to provide a machine of such class, in a manner as hereinafter set forth; wit-ha re-winding device for automatically re-winding a film, and such device having associated therewith means for not only automatically' discontinuing its operation if the film breaks, but further for automati- -cally discontinuing its operation after the completion of the re-winding of the film, and to further. provide the machine with means associated with the re-windi device to provide for the re-winding of a for inspection so as to control the speed ofthe film during re-winding so that itcan readily be inspected during such operation.

Further objects ottheinvention are to provide a re-winding machine for the purpose set forth, which is comparatively simple in its construction an arran ement, urable, compact, readily assembled, thoroughly etficient in its use, conveniently handled, and comparatively inexpensive to set up;

With the foregoing and other 0 jects in view, the invention consists of the novel construction, combination and arrangement of arts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown anemhodiment of the invention, hut it is to be understood that changes, variations and. modifications can be resorted to which come within the scope or the claims hereunto appended. 1 v

In the drawi wherein like reference characters denote corresponding parts throughout the several vie'ws:

Figure 1 is an elevation looking towards one sideof the machine and with the elements arranged in a non-re-winding position. i

Figure'2 is a vievv' similar to Figure l lookingtowards the other side of the machine. 7

Figure 3 is aside elevation of. the ma- 2, is cut awa elements thereof in re-wind- 'ure. 2.

"Fi re 6 is a fragmentary view, in perspective, of the lever elements of the in chine.

Referring to the drawings in detail, the machine includes a base in the form of a rectangular frame consisting of a top bar 1, a pair of end bars 2, 3, and a bottom bar 4, and which are of substantial width to support the various elements of the ma chine. .One sideof the support has a brace bar 6 connected to the top and bottom bars 1, 4, respectively of the frame, and that side of the sup ort to which the brace bar 6 is secured the ottom bar 4 has fixedly secured therewith an upright 7 of less'height than the brace bar 6. The top bar 1 of the support, in proximity to the brace bar 6, is formed-with a lateral stop 8, for a purpose .to be presently referred to. The top bar 6,

at a point between its center and the end bar as at 9, to provide a clearance, and sai top bar 1, at a point between the brace bar 6 and end bar 3 is also cut away as at 10 to provide a clearance. The cut-away portions 9 and 10 open at that side edge of the bar Ito which the brace bar 6 is secured. The to bar 1, between the cutaway portion 10 an the end bar 3, is formed with a cut-out portion 11 which rovided a clearance and which is of less epth than the cut-away portion 10.

Arranged within the support, and secured to theupper face of the tor 13, the shaft of which is indicated at 1 1 and is provided with .a grooved pulley 15.

, ottom her f1, are standards 12 for supporting an electric moill)- Thecircuit' connections for the motor 13 are calenergy, not shown. The elements 17, 18,

19, 20. and 21 are carried by a bracket 25, which is moored to the top bar 1, by the hold-fast devices 26. The bracket 25 de pends from the top bar 1, and the elements 17 to 21 are suitably insulated therefrom and the elements 17, 18 and 1!) are suitably insulated from the elements 20 and 21. Elm

der normal conditions the contact member 20 is out of engagement with the contact 19, so that the motor circuit will be open and the motor not operating, and the means for maintaining the contact member 20 clear of the contact 19 will be presently referred to.

Extended into the cut-away portion and prcg'ecting above the top bar 1, is a vertical y isposed standard 27 having a yokeshaped lower portion 28 overlapping the top bar 1, and the said lower portion 28 carries. a clamping screw 29 ca able of engagin thereof bifurcated for' the reception of a' pivoted reelv retaining latch 34,- between which and the sleeve 33 ismounted the reel shaft so that the reel 32 can be removed from the shaft when desired. The sleeve 33 is-carried with and rotated by the shaft 31 and extends through the bearings 30, and has arranged thereon a series of frictional coupling disks, three in number, indicated at 35, 36 and 37. The disk 36 is formed of fiber and the disks 35 and 37 of metal and the disk 36 is interposed between the disks 35 and 37 The disk 35 is fixed to the sleeve 33 and the disks 36, 37 are loose on the sleeve 33. The disk '37 has extending therefrom a lug 38, for a purpose to be presently referred to'.v The shaft 31 has its outer end threaded, as at 39, and engaging with said threaded end 39 is an adjusting nut 40 against which is positioned a collar 41 'havmg extending therein a coiled spring 42, which surrounds, as well as being connected the disk 37 'The provides for a frictional coupling action to maintain the lug 38 in an elevated position during the rotation of the shaft 31. WVhen the machine is at rest. the ing 38 is in the position as shown in Figures 2 and 4, but

- I when the machine is operating, the lug 38 is in the position shown in Figure 3. When .the lug 38 is shifted from the position shown in Figure 2 to the position as shown in F1 ure 3, it is maintained in such positiomy the frictional binding action be-- tween the disks and the action is such as to maintainthe lug elevated durin the opera tion of the shaft 31, but when t e operation of thelatter is discontinued the frictional binding or con lir action will be broken and the lug wil t en fall to the position shown in Figure 2. The lug 38 has associated therewith means for automatically discontinuing. the operation of the machine when the shaft 31 has stopped, due to the 7 i a breaking of a film or the complete unwinding of a film from the reel 32 and such means will be hereinafter referred to. The end 39 of the shaft 31 is provided with a cotter pin 44 which bears against the nut 40. The standard 27 is formed with a series of openings 45 for a purposeto be vl-presently referred to. p Extended into the cut-away portion 9 is a vertically disposed standard 46, having its lower portion 47 overla ping the to bar 1 and said lower portion 4% is provide with a clamping screw 48 which engages the top bar 1, whereby the standard 46 is detachably secured to the support; -The upper end of the standard 46 is provided with a bearing 49 in which is journaled a shaft 50, having from the other terminus of the arm 55. The

arms 54 and 56 are disposed at right angles with respect to the arm '55 and at the point of 'oinder of the arm 55 with the arm 54 a stu shaft 56 is mounted whibh carriesa grooved ulley 57, arranged in proximity to the pa ey 15. 54 is shiftably mounted on a stud 58, which projects laterally from the top bar 1. The function of the pulley ,57 wil be presently referred to. v f

Associated with the ulley 52 for the purpose of ap lying a bra 'ng action thereto, is a brake s 0e 59, which is carried on the upper end of a brake lever formed of an upwardly extending arm 60 and a longitudinally extending arm 61. The arm 60 is pivotally connected, as at 62 tothe top bar 1 and is arranged, when the brake shoe 59 is in inoperative positiomslightly forward of the motor 13. The arm 60,-- at its lower fixed therewith a re-winding reel 51. Fixed The upper end of the arm ill end terminates in the forward end of the i1 nuance 64, formed ofa stri of insulation materialoi substantial lengt and which is ada ted normal position. The

engage the contactmember 20 and ift it clearof the contact 19 thereby opening the motor circuit and discontinuing the operation of the motor 13. The lower arm'56 of the sufiiporting member-for the pulley 57 is ivota 11 Figure 2 of the drawings the brake lever is illustrated infull and in dotted lines, and also the shiftable supporting memher for the pulley 57, and further Figure 2' illustrates in-dotted lines the position of the brake lever as well as thesupporting member when the brake lever is shifted to ulley 57 ernianently contacts with the it 53, an is designed when the brake lever is shifted to nor} mal position to take up the slack in the belt 53. The positionof the brake lever 61 in full lines in Figure 2 is illustrated as with the brake applied to discontinue the operation of the pulley 52, and as the supporting member 57 for the pulley is also shifted from dotted to full lines the ition of the belt 53 becomes loose and wi 1 not perform its driving function with respect to the pulle'y52. The full line sition of the brake lever and the supporting member for the pulley 57 as shown in Figure3 illustratesthe position of such elements when the machine is operating.

Connected with the lug '38 for the purpose 7 of shifting it to the position shown in Figure 3,"as well asmaintaming it in suchposition,

, when the machine is o crating for the purpose ofre-winding a m, is a shifting lever consisting of an upper arm 66 and a lower arm 67. The arm 66 is pivotally connected at its upper end, as at 68, to the lug 38 and said arm 66 is pivotally connected, as at 69 to the forward end of the arm 67. The arm 67 in proximity to its rear end is pivotally supported, as at 70, by the standard 7. The rear end of the arm 67'is provided with an inwardly extending projection 71, which overlaps the arm 61 of the brake lever. The

' I upward movement of the shifting lever for till the lug 38 is arrested by the stop 8 which is enga by the arm 67 of the shifting lever, as clearly shown in Figure 3.. i

The pivot 69 between the arms 66 and 67 ofthe shifting lever, has mounted on the inner end thereof'a manually operated lever arm 72, having its free end provided with an inwardly extending projection 73 which overlaps the lowerarm 61 of the brake lever.

Connected to the lever arm 72, is an operatmg element 74, whiclrmay be a wire rod or a flexible member and operated either by hand or foot tread. As shown. the element 7% consists of a wire rod. The, extension 7-3 overlaps the lower arm 61 of the brake lever forwardly with respect to the overlapping of said arm 61 by the projection y connected to the arm 61,; as at 65.

71. The arm 61 of thebrake lever has connected therewith the lower end of a pullin spring which has its upper end provi ed with a hook 76 for the purpose of adjustably engaging in the standard '27. The openings 45 provide means for con necting the hook 7 6 with the standard 27.

The brake lever is maintained in inoperative position when the machine is in operation, through the medium of the projection 71 on the lever arm 67, and against the action ofthe; pulling sprin 75 and by this arrangement when the shi ing lever which consists of the arms 66 and 67 is lowered so that the said arms 66 and 67 will assume the position shown in Figure 2, the-action of the spring 75 will elevate the arm 61 of the brake lever so that the member 64 will shift the contact member 20 out of engagement with the contact 19, under such conditions opening the motor circuit and discontinuing the operation of the motor. When the arm 61 of the brake lever is shifted in a direction to open a motor circuit, the arm 66 of said brake lever will move forward so that the.

brake shoe 59 will engage the pulley 52 and arrest the action thereof.

Thefilm carried by the reel 32 is indicated at 7 7 and during the re-winding operation' the film must unroll from the bottom of the reel 32.

ln connectionwith the manner of operation after the reel 32 has been, mounted in position, the film unwinding the reel 32 has the! end fastened tolthe reel 51, and care should be taken so as not to turn the reel 51 with the film on it prior to the connecting of the end of the film to the reel 51. The shifting lever consisting of the. arms 66 and 67 is then moved to the position shown in Figure 3. When the film 77 is connected to 77' is entirely re-wound on the reel 51 and when the film entirely leaves the reel 32 the shifting lever automatically lowers causing thereby the operation of the brake lever and the opening of the motor circuit. ll the film 7 7 should break during the re-winding operation, the shifting lever will automatically lower causing the machine to dis-' continue operation.

The operation of the machine can be controlled through the medium of the manually operated member 74 which is attached to the lever 72 and when the member 74: is pulled Y downwardly to its central position, it will stop the operation of the machine, and when puiled down further will again start the machine. By the employment of the memher 7% the speed of the machine can he conrec liill' I trolled, ,due to the fact that the braking element can be controlled relative to its braking action with respect to the pulley 52 andthis enables the re-winding of the film to be slow for the purpose of inspection.

v The base can be made either of wood or metal. When made of metal it will be formed of an integral body and will also have into ral with itself parts 27 and 46, and will a so include a hangin base for the motor which will be suspen' ed from the under side. The switch will also be attached thereto. Part ma be either a grooved or flat pulley, or gear or chain. The friction may be either flat surface or friction disk;

The drag mechanism specified as having three disks must be optional so 'as to allow the use of more than three disks. These are to alternate to give one another more friction where necessary, and the additional disks are setup so as to provide for a friclv tional clutching action when necessary.

Lug 38 can be made longer than it is and drilled for adjustment of the leverage. That is, have a series of holes allowing for the changing of element 66 and placing it at different distances from the center of the disk, thereby changing its tension and allowing for the use of the machine for large or small hub reels. v

It. is obvious that the motorcan'be set up in any suitable manner and have associated.

therewith any character of transmission mechanism.

The spring 75 should be equipped-with .threader hangerfor adjustingits tension.
